Solbus Bus Factory

Bird’s view of the Solbus production plant

Solbus is a family-owned Polish bus manufacturer, which developed LNG-fuelled buses already in 2008.

Solbus buses in one of the family’s bus-operating companies.

Solbus owners have shares in bus-operating companies. The dual perspective of a bus manufacturer and a bus user was one of the main factors in taking the strategic decision to develop Solbus LNG-propelled buses.

Solcity 12 & 18 - the first series-produced LNG buses

Solbus Solcity LNG was presented for the first time in 2008. The Solcity model was awarded with the gold medal by organizers of the Transexpo bus exhibition.

The first series of Solcity LNG buses were produced in 2009.

.

Solcity buses are driven in the major Polish cities including the capital city of Warsaw.

Solbus Solcity is the lightest-in-class city bus

Solbus Solcity body is welded from corrosion-resistant steel elements grade 1.4003.Due to very light design and weight-reduction production techniques

Solbus Solcity is the lightest low-floor city bus in „maxi” class.

Stripping out of weight takes place also in the production process.

Light, monocoque design

Natural gas engine

Both CNG and LNG buses have natural gas engines

in which they burn methane!

The only difference between CNG and LNG vehicles is the technolgy

of storing fuel (methane).

We have tested LNG as transport fuel in practice

The two Solbus LNG buses have made over 115.000 km since 2009:

around 100.000 km in Ostrów Wlk. i Wałbrzych

close to 15.000 during the joint testing program organized by Gazprom-Germania and Solbus in April and May 2012

more demo runs planned for autumn/winter 2012/2013 with new, state-of-the-art, mobile, LNG station

Solbus LNG buses together with the station on A4 motorway, on the way to Cracow.

The testing program’s results - summary

LNG consumption in kilograms was by up to 10% smaller than consumption of diesel in litres, when compared with EURO 5 diesel buses used on the same routes. The savings will be even greater when compared with diesel Euro 6 engines!

LNG buses have fulfilled bus operators’ and the passengers’ expectations.

LNG technology is reliable and safe, however it requires some basic knowledge on cryogenics.

* Values close to market prices in most EU countries

1. In spite of high energy content of 1 kilogram of methane, in most EU countries, it costs 70-85% of diesel price (1kg LNG /1 L diesel). Given lower by 10% consumption of LNG (in kg) than diesel (in L) companies may save up to 40% on fuel by running on LNG. The payback period on bus operator's investment in LNG buses maybe as short as 3 years.

2. Both CNG and LNG may give additional savings because of financial incentives for green vehicles and the storage requirements that exclude theft.

3. LNG is the cleanest form of natural gas. It is never contaminated with compressor oil and contains no humidity.

LNG & CNG buses – feedback from users

LNG buses fulfil Polish operators’ expectations better than CNG buses because:

1. It is possible to refuel up to 10-12 LNG vehicles per 1 dispenser in 1 hour, which allows to operate LNG buses in the same way as diesel buses regardless of their number in the depot.

2. LNG buses have smaller and lighter fuel tanks located lower, hence the lower centre of gravity and better handling on the road (no need for extra stabilizers).

3. LNG buses have the same height as diesel counterparts so they can serve all lines in the city, also the ones under low bridges and viaducts (even 3,2 meter high).

Europe’s largest CNG station in Madrid’s EMT

THE STATION’S PARAMETERS:• refuelling time: 3 minutes/bus• capacity: 180 buses/hour• compressors 9 times 350 kW• electric generators: 2 x 1 100 kVA• investment: 6 million €

Despite high investment CNG buses are profitable for EMT.

14SOLBUS

Lower investment & running costs

LNG stations cost less than CNG ones capable of serving the same number of vehicles per hour.

Operational costs of running a LNG stations are only 10% of what it costs to run a CNG station.

„Elegantly” simple i reliable

LNG may be refuelled efficientlyeven without cryopumps (thanks to the pressure difference). Therefore there is no need for power generators.

LNG pump is a simple and reliable device compared to CNG compressor.

Fuelling buses with LNG is simple and cost-effective
